- AL1697EV1 User Guide 230VAC Dimmable LED Driver General Description This demonstration board utilizes the AL1697 Buck-boost LED driver-converter with single winding inductor providing a cost effective triac dimmable solution for offline high brightness LED applications. This user-friendly evaluation board provides users with quick connection to their different types of LEDs string. The demonstration board can be modified easily to adjust the LED output current and the number of series connected LEDs that are driven. A BOM, schematic and layout are included that describes the parts used on this demonstration board, along with measured performance characteristics. These materials can be used as a reference design. Key Features Triac Dimmable Active PFC with power factor >0.91 High efficiency >85% Single winding Low THD Good dimmer compatibility Low BOM cost Applications Retrofit Bulb, Par Lamps AL1697EV1.Rev1 Nov 2015 www.diodes.com Specifications Parameter Value AC Input Voltage Output Power LED Current LED Voltage Power Factor Efficiency XYZ Dimension ROHS Compliance 198~264V 8.1W 100mA 81V >0.91 85% 66.5 x 23.6 x 18mm Yes Evaluation Board Figure 1: Top View Figure 2: Bottom View Connection Instructions: AC-L Input: Fuse resistor-Hot AC- Input: White-Neutral DC LED+ Output: LED+ (Red) DC LED- Output: LED- (Black) Page 1 of 11 - AL1697EV1 User Guide 230VAC Dimmable LED Driver Board Layouts Figure 3: PCB Layout Top View Figure 4: PCB Layout Bottom View Quick Start Guide 1. 2. 3. 4. 5. 6. Preset the isolated AC source to 230VAC. Ensure that the AC source is switched OFF or disconnected. Connect the anode wire of the LED string to the LED+ terminal of the evaluation board. Connect the cathode wire of the LED string to the LED- terminal of the evaluation board. Connect two AC line wires to the AC-L and AC-N terminals on the evaluation board. Ensure that the area around the board is clear and safe, and preferably that the board and LEDs are enclosed in a transparent safety cover. 7. Turn on the main switch. LED string should light up with LED. DO NOT TOUCH THE BOARD, LEDs OR BARE WIRING. Caution: The AL1697 is a non-isolated design. All terminals carry high voltage during operation!
